Patented Nov. 17, 1931 PATENT OFFICE HALvon oLsoN, or MOORHEAD, MINNESOTA BOAT STRUCTURE WTTH DETACHABLE CABIN Application filed Ian-nary 6, 1930. Serial No. 418,756.

This invention relates to boat structure and detachable cabins or covers for boats.

It is an object of my invention to provide an improved construction of boat cabin which may be attached to the cockpit, or well of a boat to protect the occupants from inclement weather and from rough surf.

A further object is to provide a detachable boat cabin adapted to entirely cover the cockpit of a boat and provided with close fitting door sections which may be quickly opened when desired and disposed in non-obstructing position.

Still a further object is to provide a de- 1 tachable cabin for a boat whichis especially adapted for the use of sportsmen, such as hunters and fishermen, which will give maximum protection from inclement weather and rough surf and which is so constructed that the occupants may conveniently hunt and fish from the boat and may have a clear view from all sides.

Another object is to provide in boat structure, an inner shell including a detachable cabin and means in the inner shell for re ceiving and guiding the doors of the cabin to dispose said doors out of the way when open.

Another object is to provide in boat structure of the class above described,'an inner shell forming in conjunction-with the hull of the boat air compartments for increasingthe safety and buoyancy of the structure.

These and other obj ects. and advantages of the invention will be fully set. forth in the following description made in connection with the accompanying drawings wherein like reference characters refer to similar parts throughout the several views and wherein I Fig. 1 is a top plan view of an embodiment of my invention with the doors of the cabin raised to closed position; b

Fig. 2 is a vertical section taken longitudinally of the boat on the line 2-2 of Fig. 1; Fig. 3 is a cross section taken on the line 3-3 of Fig. 2;

Fig. 1 is a cross section taken on the line 4-4: of Fig. 2; and

Fig. 5 is a fragmentary top plan view ofa somewhat different form of the invention showing cabin doors slidable in guides which extend longitudinally of the top of the cabin.

In the embodiment of the invention illustrated in Figs. 1 to 4, inclusive, a boat hull indicated asan entirety by the letter H, which may be of any suitable type is provided having the usual keel K, bow B, stern S. The hull also has a short foredeck F and a short rear deck R. Such types of boats are used for life boats and small pleasure and fishing boats, and the main portion of the hull between the fore and rear decks constitutes the cockpit or well, surrounded at its upper edge by the usual gunwale G.

-My improved device may-include an inner shell member of approximatelythe dimensions of the cockpit having a concave bottom 6 which is spaced frointhe bottom of hull H and front and rear end walls 7 and 8 respectively which may extend substantially vertically and which are joined with the hull and the decks of the hull to form air compartments 9 and 10 in the bow and stern of the boat respectively. The walls 7 and 8 preferably extend to the bottom of the hull H and their edges have a sealed joint with the hull thereby forming an isolated air chamber 11 between the bottom of the hull and the bottom 6 of the shell. Said shell member may also include a pair of side seats 12 which extend longitudinally of the interior of the shell from end to end and these side seats preferably are constructed from sheet metal or other suitable material joined with the body of the shell to form air tight compartments 13. Thwarts or seats 14L traverse the edges of the side seats 12 and may be adjustably positioned thereon. I 7

At the medial portion of the exterior of the said shell I provide a casing or housing 15 of substantially semi-circular cross section spaced slightly from and extending concentrically with the said shell and the upper ends of said casing are open to receive the doors of my cabin, as will later be described.

A detachable'cabin is provided which may be constructed of sheet metal, canvas or any other suitable material and which comprises afront hood 16 and arearhood 17, said hoods having top portions 16a and 17 a and having closed vertical end portions 16?) and 1??) disposed at the bow and stern of the boat respectively. Ventilating cowls 160 and 170 may be provided at the upper portions of the end members 165 and 17 Z) communicating with the interior of the cabin. The lower edges of the hoods 16 and 17 are provided with inverted channel elements dependingfrom the vertical end walls 16?) and 17?) and said channel elements snugly engage the gunwale at the bow and stern of the boat, as shown in Fig. 2. The longitudinal lower edges of the hoods 16 and 17 overlie the sides of the gunwale G forming a tight joint therewith.

Each of the hoods 16 and 17 may be provided with a pair of side port holes covered by windows 18 and 19 respectively, as shown, said windows being hinged to the exterior of said hoods at points above the port holes and having clamping devices 18a. and 19a for tightly securing the windows in closed position. The end walls 16?) and 17 b of the cabin, as shown, are provided with semi-eliptical port holes and said port holes are covered by similarly shaped windows 20 and 21 respectively through which the occupants of the port may have clear views ahead of and behind the boat. In the sides of hood 16 suitable row lock apertures 22 are formed through which oars may be projected when desired for propelling the boat, and I prefer to equip said row lock apertures with annular members constructed of elastic material, such as rubber to exclude water when the oars are utilized. The row lock apertures are conveniently disposed with reference to the thwarts 1 1.

The inner and arcuate edges of the hoods 16 and 17 are spaced apart a considerable distance and are provided with opposed channel guides 23 and 24 respectively, the channel members constituting said guides also reinforcing the hoods and forming bows. Said guides 23 and 24 communicate at their lower ends with the open upper ends of the semicylindrical guide formed by casing 15 at the medial portion of the inner shell member. A pair of slidable doors 25 work in the said guides and are of segmental or arcuate shape in accordance with the contour of hoods 16 and 17. Doors 25, as shown, are provided with paddles 25a on their exterior and also on their interior to facilitate opening and closing. 1Vhen closed, as shown in Fig. 1, the upper edges of the two doors abut and said doors tightly close the space between the inner edges of hoods 16 and 17 excluding water and wind. The doors may be quickly opened by grasping the handles 25a sliding the doors downwardly, the doors being then housed in the guiding casing 15 disposed on the exteriorof the innershell member of the boat, leaving the cockpit and portion of the boat occupied entirely unobstructed, and also leaving an unobstructed substantially wide passage between the edges of the hoods 16 and 17 through which a sportsman may hunt or fish.

When the doors 25 are secured in closed position and the windows 18, 19 and 20 clamped water and wind will be excluded from the interior of the boat and an efficient ventilation will be provided through the ventilating cowls 16c and 170.

The several isolated air compartments 9, 10, 11 and 13 provide efficient means for floating the boat even though the hull is shattered in several spots. I

In Fig. 5 a somewhat different form of the invention is illustrated; Here the twohoods 16 and 17 constituting the body of the cabin are spaced apart at their inner edges, as in the form illustrated in Figs. 1 to 4. The doors or hatches are provided which slide longitudinally of the cabin in suitable horizontal guides. Guides 30 are provided extending along the sides of the gunwa-le and spaced slightly from the hoods 16 and 17 to receive the lower edges of the arcuate doors 31. A guide member 32 is disposed at the top of hoods 16 and 17 extending longitudinally thereof and having oppositely disposed channel guides in its longitudinal edges adapted to receive the upper edges of the doors 31. This guide expands the space between the inner edges of hoods 16 and 17 and is provided with a hinge portion 32a hinged at 33 and end portions 3212 fixed to hoods 16 and 17 The hinge portion 32a at its free end may be provided with a locking device or bolt 34 adapted to secure the same in place when it is desired to close the hatchway or space between the hoods. When the doors 31 are fully opened, overlying portions of the hoods 16 and 17, the hinge guide 32a may be swung upwardly and then downwardly against the hood 16 and will not impede the hatchway. The doors 31 are provided with suitable handles 31a by which they may be moved, sliding over the hoods and guided by the members 30, 32 and 32a.

From the foregoing description, it will be seen that I have provided an improved and efficien't cabin structure for boats adapted to be built into boats during the manufacture thereof or applied as an attachment for hulls already built. r I

It will, of course, be understood that various changes may be made in the form, details, arrangement and proportions of the parts without departing from the scope of applicants invention.

Because of the air chamber provisions, detachable cabin and means for excluding surf and rain, it will be apparent that my boat is especially well adapted for use as a life boat construction, as well as a boat forhunters and fishermen. The improved hatch or door construction enables the cabin to be readily ill opened for fishing or hunting without the presence of any obstructions in the doorway.

What is claimed is:

1. In boat structure, a hull, a cock pit shell disposed in said hull and spaced therefrom to form air chambers, said shell being of arcuate cross section at its medial portion, a cabin comprising front and rear hood sections having open, inwardly disposed arouate ends spaced apart at the medial portion of the boat to provide a passage or hatchway, said ends having a pair of arcuate guides, arcuate door plates adapted to cover the space between said hood sections slidably disposed in said guides and adapted to slide downwardly and inwardly beneath the arcuate bottom of said cock pit shell and guiding means associated with the bottom of said shell and communicating with said first mentioned arcuate guides.

2. In boat structure, a hull, a cock pit shell of arcuate cross section having front and rear ends tightly joined with the deck and hull of the boat and spaced from said hull to form air chambers, the bottom of said shell being also spaced from said hull and joined therewith at the ends to form additional air chambers and a detachable cabin or cover secured adjacent the upper edge of said shell.

3. In boat structure, a hull, a cock pit shell disposed within said hull and concentrically spaced thereof and ofsubstantially arcuate cross section, a cabin'secured to the gunwale of said hull and having a hatchway defined by a pair of opposed arcuate guides communicating at their lower ends with the space beneath said cock pit shell and a pair of plates slidably disposed in said guides for covering said hatchway and each slidable into concealed position beneath said cock pit shell.

In testimony whereof I aflix my signature.

HALVOR OLSON.
